I wanted to share an art-test I did a while back for Foundry 42. Mainly because I was very interested in the technique used. The scene took about two weeks.
I wanted to try out the same technique used in Star Citizen where they use face-weight normals with normalmap decals. For those intressted here is a post made by ahcookies https://www.reddit.com/r/starcitizen/comments/3ogi3o/im_an_tech_artist_in_the_industry_and_id_love_to/
Substance Designer worked great here to create quick materials that could have a lot of variation.
